Maybe a good project would be those "History of..." pages, not just for their most common words — WAR! — but to have had it run through your head, at least once, what happened in all of those places. Do you know how many pages we are talking about? The number of members in the United Nations is not the right answer, but do you know that number? It's 193. Wikipedia lists 206 sovereign states (including those with disputed sovereignty).
Let's make a New Year's resolution: Each day, read one Wikipedia "History of..." page. Will you join me? We'll go in alphabetical order, and I'll prompt you with blog posts.
